摘要: 随着国内石油公司在海外石油勘探步伐的加快,海外钻井数量日益增长,所面临的坐标转换问题突出。本文以探索研究适用于在海外油气勘探钻井设计过程的实用方法为目标,阐述坐标转换在储层横向变化快的地区进行钻探的重要意义,深入研究坐标系统的组成与特点,提出利用已有的地震解释软件、自编软件等两种快捷简便且准确的坐标转换方式,所得结果经过已知数据对比验证,误差在0.3 m范围内。将上述两种转换方法应用在西非深水区X研究区的边界成像模糊浊积水道储层的井位设计中,经钻井证实,井点位置准确,钻探结果符合预期。Abstract: The domestic oil companies of China are speeding up the pace of overseas oil exploration, and they face the problems of coordinate transformation with the increasing number overseas drilling. Practical methods are studied in this paper, in order to propose two kinds of simple but useful coordinate transformation methods, which are using commercial seismic interpretation software and self-programming software with known transformation code, based on the significance of coordinate transformation in the study area with fast horizontal change of reservoir. The results prove the two methods are effective less than 0.3 m error range verified by the known data. Those two methods are applied to well proposing of turbidity channel with imaging fuzzy boundary in X study area of deep water of West Africa, and the locations are correct under the drilling results.
